After talking to her and doing some research I found that there is an incredible lack of acai berry ice cream. You can find sorbet and sherbet easily, but no ice cream. So I set out to mimic the famous Rio Bowl -- vanilla yogurt, acai berry and granola. Adding the blueberry and chocolate was to help my poor palate.
The end result had a slight textural problem. It was a bit gritty, but not especially so. Maybe it would do better as frozen yogurt. My only guess is that this comes from the fruit itself. Perhaps if I had reduced the juice more the problem would go away. Of course, it could be the nature of the fruit. Like pineapple, it is possible that it contains something that doesn't react well with dairy when cooked. I am going to have to do more experimentation. This may be why we don't see it on the market in ice cream form very often.
Another problem was the color. Acai berry is a very deep purple. When added to dairy it turns the mixture an extremely unappetizing shade of grey. I had to break down and add red food coloring to make it purple again. The Fellow likes to be as natural as possible and hates using artificial ingredients. I implore you to find a natural food coloring as opposed to the artificial one available in most supermarkets.
As for the taste, this fellow found it to be as good as acai berry can be. I liked it just fine. It is easy to taste all the components in this ice cream and the acai berry isn't too strong. Although, my sister-in-law and her boyfriend also liked it, none of the tasters thought this was one my best efforts. Mrs. Fellow downright hated it. She said it tasted like "frozen nursing home." Ouch!
So I warn you now, acai berry can be a polarizing taste. Not everyone will love it. If you are into it already or want to try one of the most interesting new foods with potentially huge healing powers than give this one a go.
Acai and Blueberry Ice Cream with Chocolate Covered Granola
200 GRAMS of acai juice (sorry about the grams it seems strange to measure liquid in grams but that was what was on the package because it was frozen. Shame on me for not converting to to volume.)
1 cup blueberries
1.5 cups milk
1.5 cups cream
5 egg yolks
1 whole egg
3/4 cup sugar
1 teaspoon vanilla
Red food coloring
4.5 ounces semisweet chocolate
4 ounces granola
- Put the blueberries and acai berry juice into a small sauce pan and cook until the berries are really soft. Puree. You will need a half of a cup of puree.
- You should know this next part pretty well by now. Mix the yolks and whole egg with about 1/2 of the sugar, set aside. Heat the milk and cream until it is slightly steaming. Temper the eggs with the dairy, than add the eggs back into the dairy pot. Stir constantly until the mixture reaches 175 degrees F. Strain through a fine sieve.
- Add the vanilla and half of a cup of the acai/blueberry puree. Stir in thoroughly. Taste and adjust to your liking. The color will be grey. Add the red food coloring until you find a color you like. Cool, and then chill in your refrigerator for at least four hours or overnight.
- Melt the chocolate in a double boiler. Once melted, remove the chocolate from the heat and ass the granola. Mix thoroughly, then spread onto a piece of parchment or silpat to cool. Break up and large chunks into smaller pieces.
- Freeze in your ice cream machine. Add the granola during the last minute.
